Hi all, I’m trying to connect an obserable notebook to a Postgres DB my team is using - I’m getting this error. I was able to get a local DB connected to the notebook using the self-hosted proxy, now that I’m done testing I’m trying to migrate over to using the production DB hosted on AWS. I have…

Thanks all - it was an issue on our side. It seems that the CORS error was a redherring - the PG database wasn’t actually reachable via the open internet.

Hi @jnthnvctr Not knowing more details about your setup, it might help to look into enabling CORS on AWS. Unfortunately, I am not an expert on this and don’t know how CORS works for RDS… but maybe this will help: https://docs.aws.amazon.com/apigateway/latest/developerguide/how-to-cors.html As for…

All Observable notebooks run on *.static.observableusercontent.com (not observablehq.com ), where the * is the login of the notebook owner (such as mbostock). If you want to just whitelist your domain.

The team’s login. It’s always the owner of the notebook (the same as the URL when publishing), not the creator.

Just for my own understanding, you’re still using the self-hosted proxy, but trying to re-point it at your AWS database? Or are you trying to switch to an Observable-hosted connection?

It was swapping out the database connection altogether. I’d made a replica locally that I was testing on and I was just trying to point a new connection at aws!

Ah got it. It seems like we could try to make that error message more meaningful.

For team notebook’s, is this the team name, or the original creator?
